Geology of Sylt
MarMic October 2004
Relevant Gelogical Ages at Sylt Holocene - Miocene
• Holocene 10.000 - present
• Pleistocene 1.8 Mio - 10.000 B.P.– Weichsel (glacial) 115.000 - 10.000
B.P.– Eem (interglacial) 128.000 - 115.000– Saale (glacial) 128.000 - 347.000– Holstein (interglacial) 347.000 - 370.000– Elster (Glacial) 370.000 - 475.00
• Pliocene 1.8 Mio - 5 Mio
• Miocene 5 Mio - 24 Mio

Reconstruction of the geological history
• Deposition of Miocene Clays (warm conditions• Slow uplift (Salt domes?), shallower conditions with
deposition of coastal (sandy) facies: Pliocene Limonite
• Deposition of riverine sediments from a large river system in the baltic region (Pliocene Kaolin sand)
• Ice ages– Some Elster Deposits– Large Saale Deposits– Erosion during the Eem Interglacial leaving some outcrops– No deposits during the Weichsel Ice Age– Recent sea level rice, formation of the Wadden Sea and
barrier Islands

• Recent Dune formation
• Solifluction of Boulder Clay (Weichsel)
• Boulder Clay (Saale)
• Kaolin Sand (Pliocene)
• Limonite Sandstone (Pliocene)
• Clay (upper Miocene/lower Pliocene)
